Photoluminescence and Raman studies of graphene thin films prepared by reduction of graphene oxide

Broadband optical limiting and nonlinear optical graphene oxide co-polymerization Ormosil glasses

“…Two other peaks around 2700 cm −1 (2D) and 2930 cm −1 (S3) are also recorded. The as-prepared GO has similar Raman spectrum to those fewlayer GO or graphene in the previous references [31][32][33]. Therefore, the GO in this manuscript has few-layer structure.…”

Electrostatic transparency of graphene oxide sheets

“…Based on its high transparency in the visible spectrum, reduced GO has been widely researched for transparent electrodes applications aiming to replace indium tin oxide in organic photovoltaic devices and displays [4,5]. Owing to GO's intrinsic fluorescence (in contrast to pristine graphene) [1,6] and photoluminescence properties [7,8], applications have been proposed for bio-sensing [9], live cell imaging [10] and for drug delivery [11] due to high water solubility, low toxicity and high specific surface area of graphene oxide sheets.…”

Light Induced Modification of Graphene Oxide Layers on GaN Basis

“…Thus, in the Raman spectra of GO one can distinguish G peak, similar to that of graphene, corresponding to hexagonal crystal structure normal mode at about 1600 cm −1 . Furthermore, D peak (at about 1350 cm −1 ) corresponding to high density phonon states in point K of the Brillouin zone, permitted by defects, in GO has intensity comparable to G peak [7]. That is the result of presence of various functional groups intruding periodicity of GO crystal structure.…”
